#The points that are higher or lower than the whiskers of the boxplot are called outliers. Since none of the variables have points that are higher or lower than the whiskers of the boxplot, outlier treatment is not necessary in this instance.
#There are many ways to deal with outliers or extreme values, but the one we'll use here is whinsorization, in which the points above the whiskers are replaced with the maximum value of the boxplot and the points below the whiskers with the minimum value.The outlier treatment will be carried out in this manner.

#The Scores of Students Who Have Taken an Exam to Evaluate Their Potential in a Standard Role are Shown in the Histogram Above. The majority of students received scores between 55 and 60, while only a small number received scores between 95 and 100.

hist(pl$salary)
#The graph above shows how often students get paid after they get hired. We can see that the majority of students got paid between rs200,000 and rs300,000 per year, with about 15 students getting paid more than $400,000 per year.
